How To Make Death by Chocolate Cake
Follow these detailed steps to create your showstopping Death by Chocolate Cake. Precision and patience will lead to a truly spectacular dessert. Take your time with each stage for the best results.
Prepare Chocolate Simple Syrup
Pour 1/2 cup water and 1/2 cup granulated sugar into a small saucepan. Cook over medium heat, whisking continuously until the mixture starts to boil. Remove from heat and whisk in 1 tablespoon of dark cocoa powder.
Pour into a medium-sized bowl to cool completely at room temperature, then cover and set aside. You will brush this onto the cake layers right before assembly. Store any advance-made syrup in an airtight container in the fridge for up to three weeks.
Bake Cake Layers
Preheat your oven to 350°F (175°C). Grease and line four 7-inch or three 8-inch cake pans with parchment paper rounds. Set these aside. Sift or whisk together 2 cups all-purpose flour, 2 cups granulated sugar, 3/4 cup dark cocoa powder, 2 teaspoons baking powder, 1 1/2 teaspoons baking soda, and 1 teaspoon fine salt into a large bowl.
Then add 1 cup warm water, 1 cup full-fat sour cream, 1/2 cup vegetable oil, 2 large eggs, 2 teaspoons vanilla extract, and 1 teaspoon instant espresso (if using) into the dry ingredients. Whisk everything together until just incorporated, ensuring no dry streaks remain.
Divide the batter evenly between the prepared cake pans; a kitchen scale helps achieve even layers. Bake for 22-25 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs. Remove the cake layers from the oven and let them cool in the pans for about 15 minutes.
Gently run an offset spatula around the rim of the cake pans to loosen them, then flip them onto wire racks to finish cooling completely. For extra moisture, you can pop the cake layers (pans and all) into the freezer for 30 minutes to trap steam. Once fully cooled, use a serrated knife to level the top of each cake layer. Wrap and freeze layers at this point if making in advance.
Make Chocolate Buttercream
To achieve the best results in your baking, it’s widely recommended to use room temperature ingredients as they emulsify better and create a smoother batter.
Beat 2 cups (4 sticks) of room temperature unsalted butter on medium speed for 30 seconds with a paddle attachment until smooth and creamy. Add 1 cup sifted dark baking cocoa, 1 teaspoon vanilla extract, and 1/2 teaspoon fine salt. Mix on low speed until all ingredients are fully incorporated. Scrape the sides and bottom of the bowl as needed with a rubber spatula.
Gradually mix in 5 cups of powdered sugar and 3/4 cup of room temperature heavy cream on a low speed until combined. Then, mix in 1 1/3 cups of melted and cooled dark chocolate at a low speed. The chocolate should be fluid but not hot to the touch; let it sit for about 10 minutes after melting before adding.
Continue mixing until the buttercream is smooth and consistent, ensuring all melted chocolate is fully incorporated to prevent lumps. Scrape the bowl well. Cover the buttercream with plastic wrap to prevent crusting and set aside.
Assemble and Frost the Cake
Stack and frost your Death by Chocolate Cake layers on a greaseproof cake board or flat plate. Use a dab of chocolate buttercream to help stick the first cake layer to the board. Before placing each subsequent cake layer, use a silicone brush to generously soak the top of the existing cake layer with the cooled chocolate simple syrup.
Spread an even layer of chocolate buttercream on top of each cake layer as you stack them using a large offset spatula. If desired, sprinkle 2-3 tablespoons of mini chocolate chips on top of each layer of frosting for added texture and crunch.
Repeat the stacking and frosting process with the remaining cake layers. Once all layers are stacked and filled, freeze the assembled cake for about 10 minutes. This chilling step helps the buttercream between the layers firm up, reduces crumbs, and makes the cake significantly easier to frost. Then, cover the entire cake with a thick, even layer of chocolate buttercream and smooth it using a large offset spatula.
Don’t worry if the frosting isn’t perfectly smooth at this stage. Carefully press mini chocolate chips into the frosting around the sides and top of the cake until it is completely covered for a truly “death by chocolate” appearance.
Decorate Your Cake
Decorate your finished Death by Chocolate Cake as desired! We recommend using the leftover buttercream to pipe beautiful swirls on top of the cake. Fit a small piping bag with an open star tip, such as a Wilton 1M, and create elegant rosettes or borders. Once decorated, cut yourself a generous slice and savor every decadent moment!
Pro Tips for Success
Achieving a truly professional-looking and tasting Death by Chocolate Cake requires attention to a few key details. These tips will elevate your baking game.
- Use room temperature ingredients: This ensures proper emulsification and a smooth batter.
- Measure flour accurately: Spoon flour into your measuring cup, then level it off with a straight edge.
- Weigh dry ingredients with a kitchen scale: This is the most accurate way to measure and prevents dense cakes.
- Mix batter minimally: Overmixing develops gluten, leading to a tough cake. Mix until just combined.
- Weigh batter in pans: Divide batter evenly among pans for consistent baking and level layers.
- Chill cake layers: Chilled layers are firmer and much easier to handle, stack, and frost.
- Freeze layers (in pans): This technique locks in moisture, resulting in an exceptionally tender cake.
- Cover cut cake sections: Prevent your cake from drying out by covering any exposed slices.
